Auto merge of #25548 - pshaughn:docnamedgetter, r=jdm

Add SupportedPropertyNames to Document (also fix iframe getting)

Existing test of named-getting an iframe now succeeds. I added a new test for Object.getOwnPropertyNames(document) based on my understanding of the spec; that test could use a second opinion.

UPDATE: This was trying to do too many things in one PR as originally submitted. It is now using #25572 as a base, and I suggest reviewing that PR before this one to avoid duplicating review effort.
